New Polo problems - Register

[nomadx38]

Actually Audi still use TFSI on most of their models which even in their catalogues explain it as Turbocharged Fuel Stratified Injection. I have plenty of catalogues from the showroom 'cos damn I love the S5 Sportsback :p

And the Trendline Polo is a 1.4L naturally aspirated engine but is MPEFI not Direct Injection so it doesn't get the FSI badge.

Try this then

The TSi is the next generation of the TFSI engines found in the Audi TT and various other VW and Audi models. TFSI (Turbocharged Fuel Stratified Injection). They dropped the "F" to differentiate the new model engine from the old. Essentially they're the same engine with a few changes and improvements.

The word "Stratified" means "To form, arrange, or deposit in layers". With other fuel injection engines, the fuel is injected into the intake ports. With a FSI/TSI/TFSI engine the fuel is injected directly into the cylinder head which creates more torque, more power and uses about 15% less fuel than a conventional fuel injection engine.

The "Stratified" bit relates to the fact that the area around the spark plug is injected with a heavier mixture than the rest of the cylinder head which is injected with a much leaner one. Thus the fuel is injected in different layers if you like. That's why it's faster but more economical.

Exactly got to love Direct Injection. It's long time durability is to be questioned though...

Is it common for my GTI to sound like a bee hive whenever I dry turn the steering wheel?

It's kind of like a loud buzzing electrical sound. Is this normal ?

Yep, the Polo has electric steering

I believe its the electric power steering motor doing its thing, nothing to worry about.

Well ours doesnt make any noise at all when moving steering wheel

[Melon Head]

Yeah, I never noticed any buzzing when parking the test vehicle I drove.
I should collect my new car this week so I can comment further when I get it.

[readerr0r]

You'll only notice it with the windows down and perhaps something near by (wall, other cars etc.) to reflect the sound.

I can hear mine when next to a wall, which must mean its loud seeming I can hear it over the diesel racket.
